摘要： Embodiments of the invention are directed to providing a method for selecting a link for transmitting a data packet, from links of a Multi-Link Point-to-Point Protocol (MLPPP) bundle, by compiling a list of links having a minimum queue depth and selecting the link in a round robin manner from the list. Some embodiments of the invention further provide for a flag to indicate if the selected link has been assigned to a transmitter so that an appropriate link will be selected even if link queue depth status is not current.

摘要： A method and apparatus for handling, maintaining, and controlling network synchronization information emanating from a plurality of line card circuits is described. The technique described may be applied to a redundant pair of line card circuits, where one line card circuit is active, while the other is inactive. Line card activity latches are managed by means of hardware logic that may be configured at the time of line card commissioning. The activity latches are coupled to a logic element. An incoming clock signal is applied to the logic element. If an activity latch indicates that a line card circuit is active, the logic element provides the incoming clock signal as an outgoing clock signal to a control card circuit. If the activity latch indicates that the line card circuit is inactive, the logic element blocks the incoming clock signal from being passed and provides a static output level as the outgoing clock signal to the control card circuit. The control card circuit is provided with circuitry to receive the outgoing clock signals from multiple line card circuits. The circuitry is sensitive to whether or not the line card circuits are configured for redundant operation. One or more of these clock signals are then selected and used for network synchronization.

摘要： The invention is directed to a method and system for efficiently distributing Inverse Multiplexing over ATM (IMA) filler cells on IMA logical links having inactive or unusable IMA sub-links. Inactive IMA sub-links are identified during round-robin distribution of ATM data cells to active IMA sub-links. Predefined IMA filler cells are transmitted simultaneously on the identified inactive IMA sub-links when an ATM data cell is transmitted on an active IMA sub-link, thereby reducing the delay between transmitting ATM data cells.
